PAVING-BRICK.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed February 10, 1919. Serial No. 276,028.

To all whom may concern Be it known that I, WVILMAM J. MGCLAIN,

J12, a citizen of the United States of America, and resident of Bellaire, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Paving-Bricks, of which the following is a specification.

This invention relates broadly to paving blocks, and it has for its primary object to provide a paving brick or block having means formed thereon whereby it is interlocked with other similarly formed bricks or blocks, and also whereby it is spaced from such interlocking bricks or blocks.

A further object of the invention is to provide a paving brick which is adapted to be laid flat, instead of edgewise, and which is provided with lugs on its lateral edges for interlocking with lugs carried by similar bricks, said lugs being so located that they not only serve to space the brick from those bricks lying laterally thereof and in terlocked therewith, providing intermediate laterally-located spaces for the reception of asphalt, cement, or other joint filling material, but also to space the brick endwise from adjacent bricks located in alinement therewith, providing intermediate end spaces for the filler.

In describing the invention in detail, reference is had to the accompanying drawings, in which Figure 1 is a perspective view of a brick constructed in accordance with my invention;

Fig. 2 is a plan view of a fragment of paving, illustrating the use of the invention; and

Fig. 3 is a plan view of a modified form of the invention.

Referring to said drawings, the brick A is made with parallel flat faces 1 and ends 2, and its lateral edges 3 may either be parallel, as shown in Figs. 1 and 2, or said edges may be slightly inclined inward from opposite ends to a midway point, as shown at 3 in Fig. 3.

Formed on each of the lateral edges 3 of the brick are two vertically disposed projecting ribs or lugs a of V-shape, the faces of which are preferably located at right angles to each other. Said lugs project from the plane of the edge 3 on which they are formed a distance equal to the desired width of the joint, or filler space, 5 between laterally adjacent bricks, and they thus serve to accurately space each brick relative to abutting laterally located bricks.

Each of said lugs 1 is spaced from the adjacent end 2 a distance equal to one-fourth the length of the brick plus one-half the width of the joint, or filler space, (3 which is to be left between the ends 2 of adjacent alined bricks. Consequently, as is obvious, the two lugs on one edge of each brick interlock with lugs of two adjacent bricks with which said brick is associated in jointbreaking relation, as shown in Fig. 2. Further, said two lugs have their outermost faces disposed in abutting relation to the outermost faces of the lugs of said two bricks with which they are interlocked; and, therefore, said two lugs serve to positively maintain said two bricks with their ends 2 spaced apart the distance required for the provision of the joint 6.

Due to the slightly angular form of its lateral edges 3, the brick A, shown in Fig. 3, is adapted to further interlock with the bituminous or other filler provided between it and adjacent bricks.

The lugs 1 may be produced by a die in any ordinary brick-making machine, or, as is obvious, they may be formed by a wellknown repressing process.

As is obvious, the construction of brick herein disclosed lends itself admirably to the laying of paving in which the bricks are disposed flatwise, presenting an increased seating area and providing for a maximum reduction in the number of exposed joints in a given area.

As used in the appended claims, the term generally rectangular is intended to apply to the form of brick shown in Fig. 3 as well as to that shown in Figs. 1 and 2.

What is claimed is 1. A paving brick designed to be laid flatwise having a generally rectangular form. each of the opposite lateral edges of said brick having two vertically disposed V- shaped lugs thereon, each of said lugs being spaced from the adjacent end of the brick a distance equal to one-fourth the length of the brick plus one-half the width of the joint to be formed between the ends of adjacent bricks, the lugs at each side being adapted to space the brick from laterally-adjacent bricks for forming open filler-receiving side joints, and being also adapted to interlock with the lugs of two laterally-adjacent bricks disposed to break oints therewith for 2. A paving brick designed to be laid flatwise having a generally rectangular form, each of the opposite lateral edges of said brick having two vertically disposed lugs thereon, each of said lugs being spaced from the adjacent end of the brick a distance equal to one-fourth the length of the brick plus one-half the width of the joint to be formed between the ends of adjacent bricks, each lug being adapted to interlock with a lug of an adjacent brick and to space said bricks apart both for forming intermediate side filler-spaces and end filler-spaces.

' 3. -A paving brick designed to be laid flatwise having agenerallyrectangular form, each of the opposite lateral edges of said brick having two vertically disposed V- shaped' lugs thereon, each of said lugs being spaced from the adjacent end of the brick a distance equal to one-fourth the length of the brick plus one-half the width of the joint to be formed between the ends of adjacent bricks, said lugs being adapted to accurately space said brick from adjacent laterally-located bricks to form intermediate'side filler-spaces of even width and the lugs at each slde being also adapted to interlock Copies of this patent may be obtained for shaped lugs thereon, each of said lugs being spaced from the adjacent .end of the brick a distance equal to one-fourth the length of the brick plus one-half the width of the joint to be formed between the ends of ad'- jacent bricks, said lugs being adapted to accurately space said brick from adjacent laterally-located bricks to form intermediate side filler-spaces of even width and the lugs at each side being also adapted to interlock with the lugs of two adjacent bricks disposed to break joints therewith, said lugs having their outermost faces in abutting relation tothe outermost faces of the lugs with which they interlock for holding said two bricks in relatively spaced relation.

In testimony whereof I affix my signature in presence of two subscribing witnesses.
